I asked an LLM to guide me through a Salesforce process last week. It gave me step-by-step instructions, about 50% of which were fine while the others referenced options that didn't exist in the system. So I followed the steps until I got to a wrong one, then told it that was wrong, at which point it said that was wrong and gave me different instructions. After a few cycles of that and some trial-and-error, I had a working process.

It probably did save me some time, so I'd call it a mild success; but it didn't save a lot of time, and I only succeeded in the end because I know Salesforce pretty well and was just inexperienced at this one area, so I was able to see where it was probably going off the rails. Someone new to Salesforce would have been hopelessly lost by its advice.

It's understandable that an LLM wouldn't be very good at Salesforce, because there's a lot of bad information in the support forums out there, and the ways of doing things in it have changed multiple times over the years. But that's true of a lot of systems, so it's not an excuse, just a symptom of using LLMs that's probably not going to change.
